    摘要： Substantially related objects are identified by providing a first wireless sensing device having a first sensor and providing a second wireless sensing device having a second sensor. Next, comparing data derived from the second sensor with data derived from the first sensor to determine whether data from the first sensor is substantially related to data from the second sensor. The first wireless sensing device is identified as substantially related to the second wireless sensing device if data derived from the first sensor is substantially related to data derived from the second sensor.

    摘要： A multidrop network of multichannel, addressable sensing modules (ASM's), to be embedded within a composite structure, remotely powered, and interrogated by a personal computer through a non-contacting inductive link. Each ASM contains a microprocessor with non-volatile memory, multiplexer, programmable gain and filter instrumentation amplifier, and sigma delta analog to digital converter (all housed in two thin surface mount packages). An embedded mothernode includes circuitry for power and data reception (into the structure), and data transmission (back out of the structure). The external interrogation system communicates into the network of ASM's by modulating the AC waveform that delivers power to the embedded electronics. Once addressed, each ASM powers up its programmable (gain & filter) sensing channels (3 full differential or 5 pseudo differential) and data conversion elements. Sensed data are pulse code modulated, including error checking, which serially modulate an RF carrier for wireless transmission out of the composite to the interrogating computer. These advanced, micro-miniature sensing networks may be applied to a wide variety of military, medical, & civil structures.

    摘要： The novel sensor assembly is comprised of a threaded housing with pressure relief tracks through the threads that terminate at a hole through the housing and a displacement sensor. In the preferred embodiment, we have included an integral connector, a super-elastic core carrier and a Differential Variable Reluctance Transducer. Other sensor types could be used to construct a pressure equalized displacement sensor as described herein, these may include: capacitive, resistive, Hall effect, eddy current, and differential variable transformer. The sensor is attached to a keyed connector and the entire assembly is potted into the housing. A temperature probe can also be potted with this assembly to allow for multiple tasks t1o be performed by this one housing. The housing is threaded on one end to allow for easy mounting. A hole is drilled through the housing just in back of the sensor and two tracks run perpendicular to and slightly deeper than the threads. The tracks connect to the through hole. This configuration allows fluid to freely flow from the front to the back of the sensor and putting it in equilibrium without escaping from the pressurized environment. This embodiment is hermetically sealed, extremely robust and easily mounted.
